[Boost-users] [Spirit.Qi] I want to modify _val, how?

So, I was able to modify _1 (type of struct ptnode) by using a functor() (e.g. [_val = func(x, _1)] where the function will take a reference of _1 and do some modification to it and return (typeof(_1)&). Can we also modify _val placeholder on the fly through semantic action? i.e. once _val = _1 executed, then modify the _val object _________________________________________________________________ Hotmail: Trusted email with Microsoft's powerful SPAM protection. http://clk.atdmt.com/GBL/go/177141664/direct/01/ http://clk.atdmt.com/GBL/go/177141664/direct/01/
